We have a website that has two URLs (one for the US side and another for the Canadian side which is then broken into Canadian English and Canadian French). For the purposes of my question, I will write as:

www.us_url.com (US)

www.canada_url.ca/ca_en/ (Canadian English)

www.canada_url.ca/ca_fr/ (Canadian French)

To make sure people are on the correct site, what do I do if they go to the US URL with Canadian English content (e.g. www.us_url.com/ca_en/canada.asp) but I want to make sure the URL is the Canadian one (e.g. www.canada_url.ca/ca_en/canada.asp) so it shows up properly in Google Analytics.
